The guys over at GameSpy published a really cool artlice where they asked top modders of the game what they want from Skyrim. Check it out.

With all open-world games, using Oblivion and S.T.A.L.K.E.R. as prime
examples, there's an argument for waiting until the modding teams have had
their way with the game before gamers should hit the play button - but it's
not always easy to mod a game. So I went and spoke to a selection of the top
Oblivion modders and asked them; "what do you want from Bethesda to make
modding Skyrim easier?"
